The team of jailed Kremlin critic Alexei Navalny on Sunday called for massive protests across Russian Federation next week to help save the life of the hunger-striking opposition leader, who doctors warn could die in a matter of days.
A medical trade union with ties to Navalny said on Saturday he was in a critical condition, citing medical tests which it said showed that Navalny's kidneys could soon fail, which could lead to cardiac arrest.
"Navalny's situation is extremely concerning", Le Drian told France 3 television on Sunday.
He is serving two and a half years on old embezzlement charges - which he says are politically motivated - in a penal colony in the town of Pokrov around 100 kilometers (60 miles) east of Moscow.
There is growing worldwide concern for jailed Russian opposition leader Alexey Navalny, as his team warned he is now dangerously ill and could die within "a matter of days".
The European Union's top diplomats will discuss the situation on Monday, the EU's foreign policy chief Josep Borrell said in a statement, calling for the Kremlin critic to be granted "immediate access to medical professionals he trusts".
Supporters of Alexei Navalny stage a demonstration outside Downing Street in London, Britain, on 13 April, 2021.
The UK was also deeply concerned by reports of the unacceptable treatment of Mr Navalny and the continued deterioration of his health, the foreign ministry said.
National security adviser Jake Sullivan attempted to claim the Biden administration is taking a hard stance on Russian Federation over the imprisonment and mistreatment of Alexei Navalny.
"A really tough final battle between normal people and absolute evil lies ahead", they said. He has refused the treatment offered by the prison authorities.
They have pledged to ensure he survives.
"He will not be allowed to die in prison but I can say that Mr Navalny, he behaves like a hooligan", Andrei Kelin, Russia's ambassador to the United Kingdom, said in a BBC interview on Sunday.
Navalny has said prison authorities are threatening to put him in a straitjacket to force-feed him unless he accepts food.
Navalny, an anti-corruption campaigner and Putin's most-prominent critic, was first arrested in January upon his return to Russian Federation following a suspected Novichok poisoning, that is thought to have been carried out by an FSB hit squad.
In March, Brussels presented sanctions under its new global human rights sanctions regime, designating four Russian officials over their "roles in the arbitrary arrest, prosecution and sentencing of Alexey Navalny, as well as the repression of peaceful protests in connection with his unlawful treatment".
Navalny's lawyer said he missed the meetings because he was in Germany while he recovered from being poisoned with the Novichok nerve agent.
Navalny, 44, has been on hunger strike since March 31 because he says Russian prison guards are refusing him proper treatment for acute pain in his back and numbness in his legs.
